A minimalist outliner for Mac and Windows. Build deep hierarchies for complex projects without the bloat of a database
Launch Timeline: Public Release March/April 2026, Early Access Now
Copy and paste from anywhere. Fractal Outliner automatically breaks it into topics and subtopics.
Export to markdown, PDF, plain text, or web. Your data stays yours—no proprietary formats, no vendor lock-in.
Create topics and nest subtopics to reflect how your ideas are structured. Large documents remain navigable because structure—not formatting—does the work.
Rearrange ideas as they evolve. Move topics, promote or demote sections, and reshape outlines without rewriting content.
Expand and collapse sections to concentrate on the part you’re working on now. Hide complexity until you need it.
Windows at work. Mac at home. Linux on the train. Same files. Same experience.
Keep your outline files right next to your other project files, not locked away inside someone's cloud service.
Watch a quick walkthrough of creating and organizing an outline from scratch.
